SEALING ASSEMBLY AND A SEALING SEGMENT

Abstract

A seal assembly (10) for sealing an opening (12) in a wall (14) or ceiling of a building, especially for sealing a line penetration, wherein the seal assembly (10) is able to cover the opening (12) and has a passage (32) for a line (18), has at least two disk-like seal segments (16), which together define the passage (32) at inside rim portions and in circumferential direction overlap at adjacent rims (22). A seal segment (18) for such an assembly has an elastic sealing compound (26) that is applied on a carrier film (28).

Description

[0017] Further advantages and features will become apparent from the description hereinafter in conjunction with the attached drawings, wherein:

[0018] FIG. 1 shows a perspective view of an inventive seal assembly,

[0019] FIG. 2 shows a first step of mounting of the seal assembly from FIG. 1,

[0020] FIG. 3 shows a second step of mounting of the seal assembly from FIG. 1, and

[0021] FIG. 4 shows the seal assembly from FIG. 1 in mounted condition.

[0022] FIG. 1 shows a seal assembly 10 for an opening 12 (see also FIGS. 2 to 4) in a wall 14 or a ceiling of a building, especially a line penetration for a line 16. Seal assembly 10 has two seal segments 18, which are of identical shape in the embodiment shown here. However, it is also conceivable for different seal segments to be used and/or for seal assembly 10 to have more than two seal segments 18.

[0023] Seal segments 18 are each designed as flat circular sectors that describe a central angle 20 of approximately 280°.

[0024] Each sealing segment 18 has two free rims 22, which are oriented in substantially radial direction and between them define a substantially V-shaped notch 24.

[0025] In each case, central angle 20 of the seal segments is larger than 180°, preferably larger than 200°, so that free rims 22 are oriented in the shape of a V relative to one another.

[0026] A cutout 25 in the form of a circular sector is provided at the center of each seal segment 18, and, as will be illustrated hereinafter, forms portions of a passage 32 for line 16.

[0027] Each seal segment consists of an elastic and/or plastically deformable sealing compound 26, which is applied on a carrier film 28.

[0028] To produce the base material for such seal segments 18, sealing compound 26, for example a duroplastic butyl rubber mixture, is extruded onto a flat material, for example onto a transportation protection film, to which sealing compound 26 does not adhere or adheres only slightly. Then a carrier film 28, which bonds with sealing compound 26, is applied onto sealing compound 26, thus forming a substance-to-substance joint. Finally, seal segments 18 are die-cut from this plate-like material.

[0029] Die-cutting has the advantage that carrier film 28 is pressed against the surface of sealing compound 26, in addition to which carrier film 28 is drawn partly around the die-cut edges, in this case rims 22 as well as outer circular rim 29, so that these are reliably protected.

[0030] Sealing compound 26 itself is usually designed to be self-adhesive, wherein the transportation protection film applied on the back side prevents seal segments 18 from adhering to one another or to other objects.

[0031] As an example, sealing compound 26 is designed to be fire-retardant, and it may additionally contain fire-resistant additives, for example intumescent material.

[0032] At least two such seal segments 18 are used to seal an opening 12 (FIG. 2). Firstly the transportation protection film is stripped from a seal segment 18, which is then positioned with circular-sector-shaped cutout 25 around line 16 and pressed with back side 30 against the surface of wall 14, so that seal segment 18 bonds to wall 14 and if necessary to line 16 also. As is evident in FIG. 3, good adaptation to line 16, opening 12 or wall 14 is possible due to the duroplastic properties of sealing compound 26 as well as the flexibility of carrier film 28.

[0033] Then second seal segment 18 is guided, also in radial direction relative to lines 16, but in opposite direction, against line 16 and wall 14. Second seal segment 18 is positioned around line 16 in such a way that rims 22 of both seal segments 18 overlap in circumferential direction U. Thereby very good sealing of seal assembly 10 is assured at rims 22.

[0034] The size of passage 32, which is defined by cutouts 25, can be adapted by pushing seal segments 18 closer to one another or by leaving a larger distance between them. In addition, rims 22 can be positioned around line 16 in such a way that reliable sealing of seal segments 18 and thus of seal assembly 10 against line 16 is established.

[0035] Since the two seal segments 18 do not have to be deformed or have to be deformed only slightly for mounting of seal assembly 10, whereby simple mounting of seal assembly 10 is assured. Undesired bonding of seal segments 18 to line 16, wall 14 or of seal segments 18 to one another before they have reached their final mounting position is reliably ruled out.

[0036] Thus seal assembly 10 according to the invention permits easier mounting as well as very flexible adaptation to openings 12 of different size or to various diameters of line 16.

[0037] Embodiments with several seal segments 18 are also possible instead of the embodiment with two seal segments 18 shown here. These merely have to be designed in such a way that free ends 22 of adjacent seal segments are overlapped in circumferential direction, so that opening 12 can be completely closed.
